Andrew Tridgell d497d0a0a1 Rover: updates for new compass interface 2012-06-27 16:01:50 +10:00
Andrew Tridgell 7883c4a545 ACM: ArduCopter updates for new compass interface 2012-06-27 16:01:50 +10:00
Andrew Tridgell 44b7d94b1c APM: ArduPlane updates for new compass interface 2012-06-27 16:01:50 +10:00
Andrew Tridgell d9583ae5eb Compass: remove the need to call calculate() on the compass object 
the new AHRS code doesn't use calculate() and the compass.heading
attribute. Instead it works on the raw magnetometer vector. This
change removes the internal calculate state from the compass object
and instead adds calculate_heading() for use by older code that
doesn't go via AHRS.

This significantly reduces the calculation involved in compass updates

The null offsets enable/disable code is also removed, as it is not
needed now that compass offsets are not linked to the AHRS state.

Andrew Tridgell 5370f9c411 AHRS: normalize the ge vector in drift correction, and use barometer 
The normalisation ensures the error term scales uniformly with
different accelerations.

The barometer is used for vertical acceleration estimation
 2012-06-27 16:01:50 +10:00
Andrew Tridgell 7eb150a2f0 ACM: adapt the ArduCopter code for new barometer interface 2012-06-27 16:01:50 +10:00
Andrew Tridgell 4fda89beb7 APM: update for new barometer interface 
the barometer can now calibrate and return altitude values.

A 0.3 low pass filter is used on altitude to match the previous code
 2012-06-27 16:01:50 +10:00
Andrew Tridgell 53e950531e Baro: added get_altitude() and get_climb_rate() interfaces 
this allows the barometer driver to calibrate and return altitude and
climb rate values. This will be used by the AHRS drift correction code
for vertical velocity

The climb rate uses a 5 point average filter
 2012-06-27 16:01:50 +10:00
Andrew Tridgell 9fd3d15026 Filter: added 5 point average float filter 2012-06-27 16:01:50 +10:00
Jonathan Challinger 1ff9461bfb AHRS: brought DCM more inline with Bill's implementation 
omega_I applied continuously. _ki larger. Stop integrating when _omega.length()>20

The key change was the scaling of ge to ensure the error is not
quadratic
 2012-06-27 16:01:49 +10:00
Andrew Tridgell 4a91c267d7 APM: set_centripetal() is now set_fly_forward() 
this controls more than just centripetal correction
 2012-06-27 16:01:49 +10:00
Andrew Tridgell d71e82191f ACM: enable GPS in AHRS for ArduCopter 
this is an experiment in centripetal correction for multicopters
 2012-06-27 16:01:49 +10:00
Andrew Tridgell 73faaddc1b AHRS: first successful version of Bills new drift correction system 
This makes 3 major changes:

 1) fixes the scaling of the yaw drift correction term to fix the time
 constant

 2) don't integrate the mag vector over multiple readings

 3) accumulate omega_I changes over 15 seconds before applying, to try
 to prevent omega_I picking up short term responses
 2012-06-27 16:01:49 +10:00
Andrew Tridgell 0399aa9480 AHRS: update for new _fly_forward flag 2012-06-27 16:01:49 +10:00
Andrew Tridgell 2600afe18a AHRS: implement Bills new drift correction algorithm 
this is an initial implementation of this paper:
